This makes it suitable for speed and position sensing in rotating assemblies where the magnet passes the sensor with alternating poles. The open-drain output lets you pull up to any voltage up to the absolute maximum rating and allows multiple open-drain outputs to share a single pull-up resistor in a wired-OR configuration. ## 3 V supply and -40°C to 125°C range Rated for a 3 V supply, this hall switch operates from a single low-voltage rail. The -40°C to 125°C temperature range covers underhood automotive, industrial motor drives, and outdoor enclosures — the sensor keeps working when the ambient hits 125°C, though the output current capability (25 mA max) limits the load to a logic input or a small relay coil. The temperature-compensated feature reduces the variation in magnetic switch points across the temperature range, so the mechanical air gap and magnet strength don't need to be overdesigned for cold-start versus hot-running conditions. ## Active production — no LTB pressure Sourced per RFQ against BOM quantities.","metaTitle":"TLV4961-1M Hall Switch – Infineon Bipolar, Open Drain","metaDescription":"Infineon TLV4961-1M bipolar hall switch, open-drain output, 3 V supply, -40°C to 125°C, Active.
